They're great for those that like them.
I bought one with all the accessories, wind screen, lid, steamer, cover, etc and took it with me on a long adventure and never used it, much preferring my Cook Partner 22, sauté pans, and griddle. I can set up my griddle for different temp zones, too, like many say they like about the Skottle.
I wasn't a fan of how it fit into my packing scheme or galley setup, that I had to assemble and disassemble it, and just could not justify keeping it along side my other ways to cook. Perhaps if I was cooking regularly for more than just myself it would make more sense.
I sold mine, never used.
